Crypto rally spills into dog and cat memecoins as smaller tokens double in a week

Memecoins are cryptocurrencies built largely around internet jokes or communities rather than a traditional business or cash flow. Their prices tend to react strongly when traders become more willing to take risk, making the smaller tokens a useful gauge of speculative appetite.

The latest moves suggest some of the gains that began in larger cryptocurrencies are now reaching tokens further down the market-cap rankings, where thinner liquidity can produce much larger percentage swings.

Cash Cat is a good example. About $80 million of the token traded over the past 24 hours against a market value of roughly $215 million — or unusually heavy turnover for a coin of its size.

That can work both ways, however. Smaller memecoins can rise much faster when buyers pile in, but the same lack of depth can magnify losses when traders head for the exits.

Sentiment is heating up alongside the memecoin rally. The Crypto Fear & Greed Index has jumped to about 75, its highest since early October 2025, after sitting near 30 barely a week ago.

That previous move into the 70s came shortly before the Oct. 10 deleveraging wipeout, though the index measures current sentiment rather than predicting another crash.
